Answer:

Hey there! :)

Explanation:

Answers;

165lbs = 74842.74

12.01cm = 0.1201

………………….……………………………………

(Answers will be explained)

~So first let’s do question ‘A’

A. 165 lbs=?? g

~We have to use the formula.

Grams=Pounds X 453.59237

(Note: 1 lb = 453.59237)

~With that being said, we can see that the pounds in 165. So we have to multiply using the formula.

~165 X 453.59237

⇒ Equals to 74842.74

So question ‘A’ is 74842.74

==================================================

~Okay now let’s do question ‘B’

B. 12.01 = ?? m

~Let’s first see what the formula is.

~Meters = Centimeter * 0.01

Or...

~Meter = Centimeter / 100

(Note: 1 m = 100 cm)

~Okay now let’s use the formula to find the answer.

(We use the formula)

12.01 / 100

⇒ Equals to 0.1201

~Hope this helps!~

^^Good luck!^^

~Have a nice day! :P

~If you have any questions about the steps, than ask for help! I would be glad to help with anything you don’t understand! :)

^-^ Also if you need help with other questions, I might be free to answer them too!

Why factory waste should be neutralized before disposing it into the water bodies?
Fudgin [204]

Explanation:

Factory wastes are usually acidic and they pose serious environmental challenges.

If an untreated acidic waste is discharged into the river, the acidity of the river increases and this is toxic to life in the water.

On land, the acid can enter into the soil and prevent plant growth.

Acid discharge can enter the groundwater system and render it unfit for use.

Bases and a couple of additives are used to remove acidity from factory wastes before they are discharged.

Y = 57.15 − 0.5 X If Y equals 5 , what is X ?<br><br> Then is Y=3, what is X?
Fiesta28 [93]

When y equals 5, x is 104.3

When y equals 3 then x is 108.3

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

y = 57.15 - 0.5x

<h3><u>If y equals 5 what is x ?</u></h3>

Substitute y = 5 in given expression

5 = 57.15 - 0.5(x)

5 = 57.15 - 0.5x

0.5x = 57.15 - 5

0.5x = 52.15

Divide both sides by 0.5

x = 104.3

Thus when y equals 5, x is 104.3

<h3><u>If y = 3 what is x ?</u></h3>

Substitute y = 3 in given expression

3 = 57.15 - 0.5(x)

3 = 57.15 - 0.5x

0.5x = 57.15 - 3

0.5x = 54.15

Divide both sides by 0.5

x = 108.3

Thus when y equals 3 then x is 108.3

What is the molarity of the 8.76 g of Na2S dissolved in 0.500 L of solution?
AlexFokin [52]

Answer:

.224 M

Explanation:

To begin, we need to find the molar mass of Na2S

  • Na=22.99g, S=78.05g
  • 2(22.99)+1(32.07)=78.05

To find Molarity, we use the equation M=moles/Liters of solution

We are given grams, so we must divide by the molar mass of Na2S to find moles.

  • 8.76g Na2S / 78.05g/mol Na2S= .112 moles

Now we use our Molarity equation:

  • .112 moles Na2S / .500L of solution = .224 M

A mixture of nitrogen gas and oxygen gas has a total pressure of 123.5 kPa. If the
ASHA 777 [7]

Answer: 19kpa

Explanation:

The total pressure of a mixture of gases is the sum of the partial pressure exacted by the individual gases.

P total = P X + P Y

From the question above:

P total = P .nitrogen + P. oxygen

123.5kpa = 104.5kpa + P. Oxygen

P. Oxygen = 123.5kpa - 104.5kpa

= 19kpa
